Lubrication of the Meritor Clutch Release Bearing

cen mm 25.04.000

The standard clutch release bearing is sealed, and does not require lubrication. If the vehicle is equipped with an optional clutch release bearing with a grease fitting, lubricate the bearing as follows:

  1. Park the vehicle on a level surface. Apply the parking brakes, and chock the rear tires.
  2. Remove the clutch inspection plate.

    3. Note: Some clutch release bearings are equipped with a lubrication extension that extends outside of the clutch housing. It is not necessary to remove the clutch inspection plate when the lubrication extension is used.

    Note: For lubrication of the release bearing, Meritor recommends a lithium-base high-temperature grease that meets the NLGI grade three specification.

  3. Wipe any dirt away from the grease fitting. See Fig.. Use a pressure-type grease gun equipped with the recommended grease, and lubricate the bearing until excess grease purges from the rear of the release bearing (toward the transmission).

    4. Caution: Do not over-lubricate the clutch release bearing. Over-lubrication could contaminate the clutch internally, causing clutch slippage and premature failure. Do not use chassis grease or multipurpose lubricants.

  4. Wipe off excess grease and apply it to both the yoke-finger and the sleeve-bushing contact points. See Fig..

  5. Install the clutch inspection plate.
  6. Remove the chocks.
